Thanks for all your help! Having removed the head yesterday I can confirm it is a 175cc. It has a lining and the diameter of 64mm. The only problem I have now is that the carb jets have all corroded and I'm so not sure what the jetting is for a 175 as it currently has a Dellorto 24? Maybe Bill Pye is the best guy to speak to. Thanks again.

Could anyone help identify this Fantic. Its marked as a TX250/FM250 on the engine so I know its the 125cc but it has 175 markings on the tank and side panels. I know some people have fitted 200 (156cc) barrel to a 125 but not sure about a 175cc. Stickers show FM development (Fantic Motor development???) Its a rear kickstart with non-conical hubs so would I be right it saying its 1979 model? The other confusing thing is it has an alloy tank, never seem one on a fantic before so might not be original. Any help would be really appreciated.

I'm currently doing up a 1977 TY250 twinshock. I'm really pleased with the engine and steering but I've been considering moving the rear shock in a more laid down position like the majesty (I don't see the point in modifying the frame to getting more clearance etc). Can anyone give some advice to how to do this? Dimensions etc? I have a nice pair of Rockshocks at 340mm (standard) at the moment, would repositioning it mean I would need a shorter shock? Any help would be really appreciated.

Jon v8, Do you have a number?

Ive been trying to order something from them for months but the website has been down. I even tried to email Craig the owner but got no reply so guess they've gone bust. From memory he was based abroad and had a few other businesses.

Thanks for all your replies guys! I've heard of the epoxy trick. Might just give it a go in the meantime. Have any of you guys tried fitting new springs? Im realsistic I know Im never goint to get a modern fork feel on a 30+ year old bike unless I want to spent a lot of money. I heard Magicals do them but the website is down and Graig is not returning my email so guess he doesnt do them anymore. France Trial Classic have them on their website too.

Hi, I've been restoring a 1977 Yam Ty250. The forks are in really good condition apart from one which has 3 spots (quite deep) and the threads are about to give up on the legs where you bolt on the mudguard bracket. Fitted new seals and clips before riding it at the weekend and the seal has gone! My questions are although I can have them re-chromed are the forks off a mono (36mm) any better? Any advice? Im assuming I will also need to have the wheel, brakes and clamps to match? do these fit directly to an twinshock Yam. One thing I notice is that the spindle is not centrally located as on the twinshock, will this make a difference? Cheers

Does it run ok apart from the starting problem?

I had the same problem with my 05 300 Pro. More than likely its the same problem the stator. It will start fine but when the motor heats up the wires break down. I tried so many things before i got to that conclusion, ht coil, pick up jetting etc I would advise speaking to Steve at Motoplat. I sent him my stator in the post and he re-wired it and sorted the problem. Steve is an english guy but now lives in spain so just be aware if you phone him. http://www.uk-motoplat.com/home.html I sent it orignally to West Country windings but they made a couple of hashed attempt at re-wiring. I guess if you want to be sure its the stator if you've got a mate with the same bike maybe do a swap and see..... fairly sure it is though....

Check the hose isn't trapped or damaged. Also make sure your using the correct oil Dextron II. other oils have been known to damage the rubber seal in the clutch.

As far as I am aware all pro air filters are the same. Owned an 03, 05 and 06 and they were all the same.

I'm not a beta man but i've heard of a few people having problems with the key snapping if the flywheel nut is not done up really tight. First thing I would do is have the flywjheel off and check the stator. If there is any prblems with the stator I wouild suggest Motoplat to get it rewound.

You can check its the same by checking the CDI under the tank/steering head. If they are both Ducati or Kocusan you could do a swap. Cheers

I feel for you gizgrey. I had a 05 Pro 300 and had exactly the same problem. What really pee'd me off was that it ran beautifully but could I start the bugger when it was warm...... no chance. I was also told stories of changing the float height in the carb because of fuel evaporating , I also tried a bigger choke jet but still no luck. Once I had eliminated every thing fuel related I started looking at the electrics starting at the plug, plug lead, pickup sensor on the stator even eventually trying a new CDI and voltage regulator. But still no better. I ended up getting the stator rewound, as new it would cost over

I had a problem with my stator on my gasser. Steve Hardaker at Motoplat is your man. What ever you do don't bother with West Country windings, they had several goes at doing mine with no success and eventually I got a refund.

I've been offered a Raga 05 300 in good condition. I have previously owned a standard GG 05 300 in the past and enjoyed riding it but suffered starting problems of which I never got to the bottom of. I was just looking for some advice on what to look out for as I think I'm right in saying this may of been the first year they produced the Raga? It obviously comes with the Keihin carb which gives it a bit more punch but I don't want it to be too much to handle despite riding Clubman Expert? Everything I've heard about the Ohlin shock makes it sound that it much better than the standard shock. And finally did the 05 Raga not have gold clamps like the 06/07? Your opinions and advice would be appreciated! Cheers MJB

Cheers Stork955, I don't suppose you've ever had one to bits? Unless i've lost something on the garage floor mine is just a metal plate, magnet and then the mounting plate. Some people have suggested to me that there should be a spring inside???? Cheers!

I'm trying to work out if my pick up sensor / pulse coil for a Pro 05 300 with a Ducati Ignition is faulty. Anyone know what resistance I should be getting out of it?

I have a Pro 300 year 05 (Ducati ignition) and have had loads of trouble with starting it when it was hot. This has gradually got worse so decided to try and sort it. To cut a long story short its had a new CDI and Voltage regulator and had the Stator rewound proffessionally. At the moment I am not getting a spark at all!!! The only other thing I can think could be faulty is the pick up sensor on the flywheel. It is position as most people suggest on this forum around 0.7mm. I have also had the sensor to bits. Could someone tell me if there should be a spring inside? All I can see in mine is a small metal plate, a magnet and the fixing plate on top. GASGAS do not sell these seperately to the stator and want to charge me over

Thanks for that Jon. I've gone out and bought a multi-meter (must admit i'm no sparky) and tried to test the resistance. The result I got some pretty strange readings, way above what you quoted. The weirdest thing was that depending which probe i used gave different results, for example red probe on A and Black probe on B would give 1.44Mohms and if I swapped them around it would give a reading of 2Mohms. However this was only on a few of the combinations some were consistant using either probe as I would expect. Do you think i'm doing something wrong or is this a sign of the ignition failing? I've gotta admit the gap on my current plug seems a lot bigger than you suggested. what is the best way to reduce the gap without damaging the plug? Cheers Martin

Jon, I have put a EIX plug in it a few months ago and a bigger choke jet (80). It still plays up when hot. I've owned a 300 before so I know that there is a nack to starting them (normally in neutral and a big hefty kick on the top of the stroke does the job). However this one is something else. I have got the pick up position as suggested but it still has trouble starting. When it runs its fine, I never have a problem in a section. The other thing I have noticed due to the change in rules over here in the UK (we can now stop) I have noticed a few times the engine dies on me when i have the clutch in and just balancing the bike eg just on tick over. I guess my question is do you think its electric or fuel related?

I'm having trouble starting my gasgas pro 05 300 when it's warm. I've tried a number of things to sort it including new stator, pick up and voltage regulator as well as the checking carb jets. The only thing I haven't tried is a new cdi ignition. I've got a ducati on mine and I've found someone who is breaking a 250 but it has a denki. Does anyone know if this would do? If so is there a different voltage regulator or wiring to go with it? Cheers

any idea if it's ok to practice in the evenings? I don't live far away and was thinking of a cheeky summer evening practice?

Can anyone tell me the pros and cons of an ohlin rear shock over a standard gasgas shock?

Hey I live in Worksop. I haven't manage to find anywhere. Most people I ask suggest Braken Rocks as I am told they do practice days. I'm interested to know where the pit tip is in Harworth, could you give us directions DaveT? BSSA Clud run a few trials in the area maybe going to one of their trials and asking a few people might help.
