guys

This is how I do it. Rock solid.

A friend of mine who saw it happen, said the tank cap was indeed loose.

It seems that the weather will be good on sunday. Looking forward to it.

I doubt that there's room enough for a 13 T sprocket, even a 12 might come to close to the flywheel cover. My 300RR came with an S3 36T rear sprocket, might be a better idea, or a 38 which is readily available.

Thanks for the link!

No, the fuel doesn't spill out because no fuel line is opened. You have to remove the complete injector with the fuel tank. Due to the new lay-out of the fuel line, you have to remove the breather hose from the valve cover. The rest is described here: http://montesa4rt.nl/data/2016_300RR_kit_300RR.pdf http://montesa4rt.nl/data/2016_300RR_kit_full_power.pdf

Having some fun

The things I did when I got my 300RR - mount case saver, waterpump and coil cover - change rear sprocket for a 43T (best use a half chain link) - Change rear brake disc for a Galfer one - ad water resistant grease to link, wheel and steering head bearings follow the instructions in the manual for running in. Enjoy!

I think it's (HD) polyethylene but PTFE should be fine.

I wonder how the 300RR is gonna cope when it gets hot this summer. It's only 12°C outside, and the fan already kicks in every 20 seconds. Big radiator from H&D Racing might be a good idea?

Strange, I never had problems starting my 2008, 2015 or my new 300RR when its in gear.

Sweet voice!

Nope, it turned out to be a bad crank shaft and gearbox bearing, to much play in the big end and the piston play was at the max. limit. http://www.trialscentral.com/forums/topic/57939-rebuilding-my-bultaco-159-engine/

I live in Belgium actually. Normally the dealer would remove the lights, exchange the throttle body and such , but because I like to tinker, I'm doing it myself.
