would you use rubber mounts or not ?
some say yes some say no
im not to sure which way to go on mounting my bike engine?

Think lot of people use polybush's.. though i guess it's all a matter of your own wishes

My blade was partially poly bush mounted using the ST cradle, the R1 is solidly mounted.
Ive noticed a little bit more vibration with the R1 over the blade, but not a huge amount so personally I would mount solidly again in future, much simpler and potentially could add a bit of extra rigidity to the engine bay area.

but do it to rigid!

on my car one engine mount broke,

when i was driving at 5mph on an land road..

now i have added an couple of bars and now i would say its bullet proof!

altough i think that an engine in rubber would be better for the engine..

also it would make the drivetrain less demanding on the engine...now every shock and vibration is passed to the bike's gearbox...else it would be the engine mounts wich will take away sum and the gearbox...

Tks

interesting point at aintree the other weekend there was a guy with a rubber mounted engine who thought that was the reason he couldnt get 5th and 6th on the track at speed at low rpm on jacks all 6 gears on the track only 4
just a thought

in fact if you use rubbers you should apply them to all your shift system and drive train to..

becase how the hell can the engine move if the gear changer is rigid??
i know its an bit but i don't like the idea that the change lever is dancing an bit..it would deffenitly move the internal parts pushing an bit the forks.. or in extreme situ bent them... off cours all depend on how much movement do we have...??

the solution i see for that guy is go the cable shift route, with 2 brakecables
1 for gear up and one for gear down...
then the attach points should be made on an piece of benden sheet and that with a n bit longer bolt some where on the engine...(including the adjuster)..

also the drivetrain cant be rigid then??
