Hey guys, some of you may have seen in my project thread I'm having problems getting my Gas Gas contact 250 (1994 ish) figured I stand more chance of getting ideas on here rather than my small build thread.. After rounded of kick start splines, choke levers snapping, new kick start snapping.. I finally have the bike so it kicks over! I have spark, after a good few kicks the the plug is wet when removed.. Have tried choke on/off. Covering part of inlet, throttle a little open, fully closed.. Staying brake cleaner into carb while kicking.. Nothing! I have been told to turn it upside down to try drain any fuel in crankcase out of the spark plug hole.. Anything else worth trying? I'm kicking it over as shown in the video.. Kick it gently so it just passes TDC then give it a good strong kick (using my weight not leg muscle) Thanks..

How would you know your getting too much fuel? After a few minutes of kicking the plug is wet? Clean clear fuel? Will try that tommorow.. I'm about at my patients limit at minute I'm not in a position financially to be able to book it in a shop for investigation as I have just changed jobs and haven't been paid for 6 weeks

Grrrrr!! I have spark, I have fuel.. Why the **** is it not starting?

Aft another 50 minute drive to get another kick start (super thin light alloy again lol) fitted that.. Went to kick over and the back of the kick start catches!! Again.. I managed to laugh it off.. Spent an hour filing it down so it now clears the frame.. So... Kick start is on.. Carb is rebuilt and on.. New fuel and oil.. New spark plug.. I don't dare try it! Haha! Here goes.. Watch this space! *please start*

Back home from work already. I love this job haha, Going to try get the kick start together and get the carb back in and hopefully will be running after an hour or too worth of of work!

Problem is I do not want to chuck money into to then realise the engine doesn't run good, suspension needs rebuilds etc. so just want it running and going to try it for a few days and then go all out. Rather than waste £100's on it and still have a bike that doesn't run and needs an expensive engine etc Was hoping to be off work today as I have been all week (joys of working offshore!) but I'm going out today gutted. Hopefully some late night progress tonight

Haha, it has some stupid carbon fibre dip stuff on it that was half sanded off. It was so light I was expecting it to break to be honest, but more than one kick.. It didn't even get past the compression point! As long as I'm better on the pro haha

I sure do! as you say, hopefully be worth it only reason I haven't gone insane! I'm hoping to have it back in immaculate condition, road registered and then buy my self a GG TXT Pro and give this too my dad so we can use it at weekends (it was him who bought it for me all them years ago after all!

Some good new/mixed with bad news (surprise surprise!) Managed to source a kick start lever! Was massively light though.. Fits perfectly, same splines etc.. One kick later... At this point I don't know how I done it but I actually laughed! How is it I can have so much bad luck?? I have stripped this and my new one down and going to fit the base to my old lever so I have the new splines and my strong lever. Just hope this doesn't then break the base section! Just need to drill out my old lever to fit the base into it as its too thick to fit in at minute. Have the correct spark plug now too. Also managed to find a new bleed nipple for the clutch and having the rear brake done ASAP. Hopefully once this kick start is on I can refit carb and get her running, then find a gear lever as its missing (splines are knackered too but hoping I can clamp something on!) then test ride and if all goes well, full strip down/clean/powdercoat/rebuild! Also enquired about registering for the road too!

Snap... There goes the clutch bleed nipple too. I give up lol don't even dare try front! Lucky the clutch one is part of a banjo so should be easy to source.

Quick clean.. Only to get big bits off as don't want water damage or damage seals! Engine casing looks clean still! (Bloody kick start) lol

Well, as you would expect.. More problems! Liquid metal is crap, its still a liquid! So cleaned all that off! Drilled the bolt out and I'm now waiting for a mate to bring me an M8 high tensile nut and bolt and try clamping it up mega tight! May try stick in part of a coke can as I read online! Hopefully also getting the helicoil kit today if the shop stocks them! Now about to pressure wash 7 years of dust (and nests) from the bike so will have some more full bike shots in a bit. Also good news, the frame corrosion.. Majority of it just comes off with wire brush. Will get the wheel and drill on it later and polish it up! (Once I get it running of course or its wasted time) With regards to spark plugs. The plug in it is NGK with a 5 temperature rating. I can only get 4 and 6 temp today in that plug. Which would be better to try while I wait for a 5? Hotter or colder? Thanks.

Hey guys, sorry to jump on the thread a bit but how would I go about doing this to my 90's Gas Gas 250? Cheers

Hey guys, figured I would make a little progress/build thread so you can follow the build if you wish. The background of the bike - I got the bike when I was around 14-15 (I'm now 22) I used the bike for around a year religiously every Saturday down Corton Trials Centre. I can't remember why but after one Saturday I drained all fuel etc and put it away as I wasn't going to use it for a while.. 7ish years later I have just dug it back out! She hasn't held up to good, frames full of surface corrosion, lots of niggly problems I'm battling which I will list as I go along This was her.. Straight from the garden to my trailer. First time rolling in 7 years! Got her home and set about the usual, changed the fuel, stripped the carb (was full of goo!!) new plug. Tried kicking her over... Nothing.. Wouldn't start or even try too.. I then realised the choke switch was broken and not actually lifting the choke! Ordered a new one which has just this minute arrived and just fitted that.. This is why the old one was seized.. New one fitted.. Few pics from the strip down showing the mess! So that's ready to go back on.. Tried bleeding the rear brake as there was no pressure there at all.. Things went from bad to worse! Removed the nipple (after spending ages unseizing it) revealed some unpleasant looking brake fluid! Now the bleed nipple... The thread on the caliper is beyond repair! I'm going to helicoil a 10x1 thread in and hopefully that will be ok! My biggest challenge so far.. The kick start has rounded! I have tried multiple levers but none with same size spline hole As I'm unsure how much work the bike needs, I want to just get it running and go from there so don't want to splash out 90+ pound on a lever for it to still not run properly so I have just liquid metalled it to the splines and going to nut and bolt after I drill out the snapped bolt today! That's it for now.. Its now time to go try get it back together Will it run today?!?

Hmmm, interesting, never heard of this. Sounds silly but have you tried it since? With a different temp? May be worth cleaning the slide up with a bit of fine grade sane paper and try it again if it has any gunk on at all?

Hahani was thinking that coop, problem is as its not starting at the minute even with a kick start I can see it being ALOT of hard work and potentially jot starting haha Hopi the repair will work at least enough kicks to get it started and have a quick ride to check for anything else

Haha I'm a bit happier now. £7.50 helicoil kit for caliper, and I'm going to hope the liquid metal holds it! Just hope I can drill through the snapped bolt easily enough! Cheers

This is the caliper type needed also.. AJP is the make.. http://www.ebay.co.uk/itm/Gas-Gas-Contact-Rear-Brake-Caliper-AJP-/181036143464?pt=UK_Motorcycle_Parts&hash=item2a26985368&nma=true&si=0wnMGvHzYIzptsXiHAO4GUS%252BpW8%253D&orig_cvip=true&rt=nc&_trksid=p2047675.l2557

Right guys, few updates. This is going from bad to worse. I have alot of patients but this is getting me close to giving up! Went to bleed brakes.. Rear nipple was seized solid.. After 10 minutes of carefully removing (loosing, tightening up with lots of WD) it come out. The brake fluid looked like mud, thick and brown (this was changed when I last used it!) shows what time can do to the fluid! Bleed nipple was blocked so spent ages unblocking this, thread was damaged at the end but was hoping it would go back in.. Well, it didn't! The thread on the caliper (which I think is made of some kind of cheese?) is dead totally, I tried cleaning it up but its way beyond repair! So now I need a caliper.. This isn't going to be cheap.. If I can find one at all! Which at the moment I can't! Next problem, kick start still.. Went back to the shop today to try exchange the lever for a bigger one to fit. Surprise surprise they had nothing and can't source anything either. I tried fixing mine the best I could.. I have cleaned spliness and put liquid metal in the splines. I know this isn't ideal but if it gets it started I don't mind and will fork out the £90+ for a new lever. Problem I have is I just don't want to be throwing money at it getting it running for me to take it out and keep finding problems. I'm already thinking of buying a newer bike! Anyway.. Back to the kick start.. Doing the pinch Bolt up.. Snap.. Great! So drilling that out and will use nut and bolt for that tommorow.. On the bright side.. The choke switch should be here tommorow so as long as I can sort/bodge the kick start I should be able to get her running tommorow. Any ideas on the caliper or kick start lever though guys?

Just seen a Gas Gas video on youtube (official) and they say use dot4. Will do this tomorrow. Any tricks on bleeding them? On another video I have seen it says about gearbox oil.. Using 5/30 car engine oil? Anyone heard of this? :s

I'm not sure on what's in it to be honest. Same with coolant, why I'm a bit wary about doing it yet. Just seen your in Norfolk, where abouts? I'm local and would be good to meet another rider!

Not sure if its worth trying to clean mine up and re try it. Just worried about stripping the engine side as that's fine at minute. Bloody bikes! Lol

Jesus. That video is rough. What causes it?

So it only turns quarter of a turn? Yes coop, the video helped massively too. Unfortunately the kick start I got does not fit. Its too small, yet another hold back Choke switch ordered and hopefully exchange the kick start for a bigger one and try that. Really want it running for this weekend. Then just need to bleed the clutch and rear brake as there is nothing there at all. Just soft! Normal dot4 ok?

It sounds silly as its never happened to me but.. I this caused when you drop the bike and it lands on throttle grip and holds it open?
