List of known modifications or upgrades (Read 11685 times)

wintsoz Ex Member	Re: List of known modifications or upgrades Reply #10 - 27.07.18 at 01:29:10 Hi Greg & TR 1 fans I own 2 x 1981 xv 1000 solos and currently building a Pre 85 Sidecarcross with a Tr 1 motor to race in Germany - Klienhau 2020. I have found a 2010 XVS 1100 complete donor bike 9000kms for the suggested engine mods. Is this the correct model for the Crank, Barrels,Rods, Heads . Also do the gears clutch & starter assembly fit the 81 Tr 1? I see a company in USA https://www.pacificcoaststar.com/pcs/v_star_1100_engine.htm. Im interested in their x3 Cam and dual valve spring conversion & the Keihin Flat slides. Have you heard any reports about their gear? Yes Im after 90 + HP Regards Darren

The liners are a bigger O.D. and as such the cases need to be bored out to suit or the liners turned down to fit the cases. Gearbox and clutch can be fitted to TR1 cases, but they are a different spline pattern on the clutch hub and as such you're then limited to stick with the BT/XVS parts. The starter on the XVS is inferior to what was installed on the TR1. The best starter bendix is to be found on late Virago 1100s (the version without a spring). The oldskool-no-hassle swap are Virago 1100 parts as they are a straight swap. Additionally those also sport a heavier crank, which might be beneficial on a sidecar. Cheers, Greg

I notice the old filter had a slot in it and the new one different (no slot) I looked at it and cut a slot on supply side to make it fit...anyone heard of this ?

Can you post a picture of the filter with the slot? The filter fits without cutting slots into it, provided that you mount it the right way. The opening belongs to the outside. Stick it on a finger and then put it into the housing, then it´s right.
