Thanks any idea about how to get the nut off first? Is it am impact gun job?

Hi I need to split the cases on my 4bl engine as either my big end or side bearings have gone. How do you get of the nut and then pull off the flywheel - its different from my other bikes with the usual centre screw puller?

thanks a lot

@MadGyver Many thanks for the info. I think I will see if I can get a 3bn cylinder.

Is the pv the same as a 3mb?

Thanks

Thanks but I will be keeping the 4FU.

Does anyone have knowledge on the 2RH top end fitting?

Hello

One of my DT's is a 1988 with the early crank, the stroke is shorter at 50.0 vs 50.7 for the later bikes. It however has a 4FU top end which has been fitted without a base gasket (case sealant instead) to correct the stroke.

It goes well but it always niggles me that it does not have the correct top end vs crank and could have slightly off port timing as a result.

Does anyone have a (mostly useless to anyone else!) 3BN cylinder and PV they dont need I could buy? I have also seen some photos of DT's fitted with a 2RH top end from a TZR (which has the same bore/stroke as the 88 dt). Can anyone confirm if these are a direct swap, does the lower cylinder bore match the DT cases?

I could swap out the crank but its a lot of effort for not much gain (if any)

Any help or knowledge on this is appreciated

cheers
