Hi guys, ive sold the enduro bike and got myself a 2000 montesa 315r! Went out on it yesterday for the first time and it was wicked! Got some probs with the old girl tho, its running like a bag of nails!?!? Its hunting on tick over and stalls, wont really rev either! Have taken the carb off and will give it a clean tomorrow, have cleaned the air filter to.. I no nothing about this bike, has anyone got any info on carb settings, what mixture to run it on, what gear oil to use and how much?? is there a manual i can download fom anywhere! Need a cheap helmet to if anyone knows where to get one?? I am lovin the trials my only regret s not selling the expensive KTM sooner! Everyone should have some trials iron in the garage! Thanks in advance!

I've done exactly the same thing. Had a WR450, then a YZ250 crosser which was sadly stolen from me....grrrr.... so I've decided to try some trials and I've bought an 01 315r. Mine will only idle nicely with the screw turned out about 3 turns. I'm told this is too much, but it seems to suit my bike. Fuel/oil ratio for me is 70:1, seems about right. I took some advice about gear oil as mine suffers from a sticky, grabbing clutch. The majority of people told me to use ATF, which I did, and it has improved significantly. 550ml does the job.

Air filters are not dear, if yours doesn't clean up nicely then bin it for a new one. A new plug wouldn't hurt either. When you say it wont rev, if you mean it seems to pick up slowly then it may well be right. They have a huge flywheel compared to an enduro bike so will feel way different. I know mine does.

Hope that helps, enjoy your new ride

i have the manual in pdf i scanned myself but its 46.9mb so ive uploaded it to rapidshare for those that req it just click the link to go

Looks like you may be sorted other than the helmet question. If you want a cheap trials helmet I reckon you can't go wrong with the Xpeed (or is it Xspeed). Around 40 quid. Not the lightest, but not over heavy and certainly not ugly. At that price you can drop them in a bucket and blast them with a jetwash after every couple of trials. Probably not recommended by the manufacturer, but I have two of them that still smell fresh even with my fat head in them every other week

Acdelco, sounds like your bike is doing the normal clogged slow jet lean surge. I've had my '00 315r for a year now. The slow jet clogged very easily, I must have cleaned that carb 5 times the first month. Stock setting on the air screw is 1 turn out. If the jet is partialy clogged turning the screw in all the way will help. I ended up drilling the jet out with a small jet bit. It was a lot better but still clogged again, so I drilled another size larger and all has been well. But the screw is 2 and a half turns out. Another thing to check is the o-ring on the air adjustment screw, if it is cracked it will leak causing the same problem as a clogged jet. Elf 740 oil is the best for the gear box, it is expensive but the clutch might actually work. I didn't sell my enduro (wr 400) but I don't ride it very often since I started trials. If you don't have knee/shin guards get some and don't ride without them. Every time I ride without them I land on my knee or shin on a rock. So far every time I think I've gotten better than the bike I learn that with the proper technique the bike will do what it is suppossed to do. Have fun!

I forgot to mention; I run 105 octane fuel. Running pump gas makes the piston sound like someone is trying to hammer the crap out of it.
