[315 wont tickover]

The floats are the problem then, look at why they block the fuel & go from there.

[1999 TXT 321 Running problems]

Could also be a stator problem, ok when cold but fails when warming up. Had this happen to mine.

[93 JT250 Fork Clamps size question]

The 93 JT has upside down forks.

[2019 gasgas front suspension adjustment.]

No manual with the bike?

[Gah. New ignition, new problems.. TXT300...]

Have you strobed it to see what the timing actually is?

[Won’t start but occasionally pops/bangs]

Or it is spinning but its shifted to the point where the timing is screwed.

[Front folks]

If the previous owner thinks that's ok then I would be thoroughly checking the rest of the bike before going out on it.

[How far are your forks through the yolks?]

Maybe your settings are too soft? ive had 3 betas & none of them are prone to tucking the front, what sag are you running?

You guys seem to be having your own argument.  I just wanted advice on fixing it

Sorry, I think we've finished now

[1994 jt125 problems]

Now im thinking was the 200 a 163cc? Im really starting to lose it now.

[1994 jt125 problems]

Yes I know very well the differences between the GT & the JT, I had new gassers in 93, 95&96. You are absolutely correct in that his bike is a GT frame. I just cant help remembering something about the 160 using different forks or frame for the year, the official brochures say otherwise though so have to concede it may have been something one-off using left over parts maybe. Time has blurred the memory! Although I do remember them being 143cc though so that's something you've forgotten too

[1994 jt125 problems]

The 160 used the previous years frame but with the 94 forks back then I believe, so it's possible you are right bungle.

[Total rookie]

Unless you love it or you are absolutely broke then get rid of it & get something newer & more reliable, these bikes now are very old & can be a big headache to fix multiple problems. Its worth about £300 max.

£1500 gets you a way way better machine. I understand if you have a very limited budget however.

[Oil]

Can also recommend nano trans in the beta, best oil I've used for the clutch.

[air box blocker for evo ?]

Stuff an old rag in.

[TX300 oil ratio]

Nice bike, crying out for a set of original mudguards though, hopefully someone will produce replicas one day.

[Gas gas 1991 ? Trials 250]

Wow, that's a rare old beast. Almost certain its a Delta, plastics would originally have been white (1990) or green/purple (1991)

Looks like a delta engine plus has other delta parts on it so pretty sure that's what it is.

[Gas gas 1991 ? Trials 250]

Can you post a picture of the bike so we can see exactly what you've got?

[2013 Beta Evo - Adjusting the Air & Idle]

Take the fuel line off, then operate the tap so you can check if the tap is working, it takes longer than 30 secs for the engine to use the fuel in the float chamber at idle.

[gasgas 250cc trails bike 1993 gt series help]

Who did it & did they use new o rings/gaskets? Has it had this problem since the top end rebuild? Think I’d be having the head off after checking the impeller.

[gasgas 250cc trails bike 1993 gt series help]

When I had one of these there was an issue with the header tank cap not sealing. This in turn allowed boiling/overflowing of coolant. Some riders fitted a large jubilee clip round the cap to squeeze it tight against the header tank threads. As above though, it could be any number of things on a gas gas of this vintage, they weren't built well back then, its a brave move buying one now.

 

[Just bought 2016 beta evo 300 , few questions??]

As above, 80:1 full synthetic & nano-trans gearbox oil. No clutch issues using that.

[knee/shin pads with side protection?]

I have some fox launch enduro MTB knee pads. Ive worn these for all day rides on the mtb & theyre really comfortable, not bulky at all.

Was thinking about using them for trials when I get back to riding.

If world trials results influenced bike sales we would mostly buy montesa 

Plus the TY mono would have been a huge failure!

[Sherco 290 2011]

If it kicks back a lot when starting have a look at the timing/flywheel.
