As above, buy copy of the book, separate one for engine, it’s worth it’s weight in engine oil. Explains everything including improvements. Having had problems with clutch slipping on starting from cold I run chaincase dry. The Oil is only for the chain. As bike doesn’t do road work at constant higher revs I just use chain lube on primary chain, sprayed onto it via breather pipe hole. Works for me.

Beta 4t with one tooth less on front sprocket. Amal 80/200 throttle slows throttle response, softens it noticeabley. Beauty of this throttle is cable just swaps onto the spare hole on throttle cam and tension then perfect (it’s easy to see when look at one)Doesn’t need anything else, bike is very forgiving and pulls so well in any gear. I haven’t rode a montesa 260 but friends with them say my beta is “softer”. Owned two and never had any issues or had to adjust valve clearance

If concerned check engine and vin number against v5 and that sellers details match v5. As above, hpi check Are there 2 sets of keys

You mention 4 stroke, 4 stroke beta is VERY soft in power delivery. Very forgiving and easy to ride and maintain. Certainly can’t fault the montesa for build quality, it’s all personal preference and not everyone likes 4t but thumbs up for the beta, particularly if you put slow action throttle on.

I can recommend soft brake linings used by Villiers services. Simple to book relining on the website just send old shoes in

most normal bike racks seem to have similar total weight limits of 60 kg, but would need to check if there is a limit per single bike, the individual frames aren’t the strongest. Could you get Dave cooper rack delivered to someone here or in N Ireland then forwarded to you by courier? Or possibly a courier who delivers to you from England would collect directly from Dave cooper instead of their postage

Cheers Brian I love my look of shock/relief/ amazement on cleaning the gulley, great photos on a great day

Francetrial classic seem to have magicals springs.

In motion aren’t stocking them. I recently spoke to them and also left message with Steve from Yamaha majesty to see if he will still be supplying them.

Have you actually tried riding a 125, not much difference on paper but my dad, at 87, has a 125 gasgas and it feels lighter to ride than a 250. I know not why but definitely feels lighter and easier to manoeuvre and much easier to start. kids on big wheel 80s can certainly do plenty, about 3/4 size of full size bike I think

Check out kellycarbon. They are actual carbon fibre so cost more than the plastic carbon look.

I always found oset themselves very helpful on technical queries. Phone number/contact form on oset/gb

I assume you mean the likes of a Dave Cooper rack, If I only need to transport 1 bike I use a bike rack on back of freelander. Fantic is perfectly safe/secure and well under the nose weight. You can check the speck for Navarro but pretty much guarantee to be fine.

I’ll agree with all the above. I’ve had 2 evo 4t’s and never Needed carb off once.

Have you seen the worx cordless jet wash. I have one and works great. Plenty of power and if you don’t have water you can use it from a river

I’ve got NJB ultimate on BSA C15 and Fantic 240. Personally I find they work very well and I’m 90kg, Now I’m trying to remember if they were soft or super soft, I just rang and gave them the bike and my weight so they could build them. Reasonable price too plus adjustable length. Had a pair of Falcon shocks and likewise rang the company and gave them bike and my weight. They were super soft and were fine on C15

Was it a home made lipo conversion or pack from boost bikes. If homemade then possibly issue with the battery monitoring system? sure someone with electrical know how will explain. Only similar issue we had with an oset it was the controller/throttle unit kept intermittently cutting out. Had to replace it

Agree with the above. Start at forks, is the front wheel true with handlebars straight, check clamps in case forks have twisted slightly. The back wheel has pretty rubbish adjustment as it doesn’t have snail cams. Best way is to put bike on stand and adjust each side with the chain tensioner bolts at rear of swinging arm until the chain is correctly tensioned and wheel is running true. That is fiddly to get spot on as it can change as you tighten bolts. Just takes bit of time but if it’s out it makes back wheel run slightly out of true which puts extra pressure on the already feeble front sprocket. While your on check that tiny front sprocket, cheap enough to replace, we had one which, when it got worn just disintegrated

Unless silencer is wrecked you could clean it out and re pack it, not sure if the end comes off the Rev 3 to get old material out, roll of silencer repacking material is very cheap. 2 stroke silencers can get very clogged with unburnt oil.

Don’t know how postage would work out for you, but look up Richard Allen trials parts or trials bike breakers uk. Both good source of used parts if there isn’t anywhere similar near you. Definitely want 70:1 for oil, putoline tt trial pro or similar. Brake/clutch levers are pretty standard, available in usual range of colours, prices. Google search for rev 3 will show you plenty of choice to suit grimeca master cylinder

18 primary, 14 front and 60 rear is as good a place to start as I found. Can adjust rear by couple of teeth if not quite what you want.

Should be like the scene in Forrest Gump where he strips rifle and reassembles it blindfolded in seconds. Carbs on the table and go.

I wouldn’t be over concerned about the lights, just a guide having had a few Main thing is how long does it last before power tails off, depending on type of riding, hills and flat out riding take their toll

Is it a new or used bike, when fully charged check the voltage of each battery separately, a good battery will show about 12.8v and a dead one 12v, sounds strange, but if one is dodgy that would be my first thing to check.

If you want to stick with Amal then a 622 concentric is the one I have always used and is the one specified/supplied by Amal for a C15 I have a spare perfectly good used one but I’m guessing you’re in Australia. I’ve seen trials type pattern on 20 inch C15 wheel maybe ok for green lanes but not a trials competition tyre,
