It is, but not for a Genesis engine. Three-in, two-out.

3 shims had been shaved by what looks to be a grinder, mother of god

I haven't come across these type shims before, there a bucket shim within the bucket! 7mm in diameter and 2.2mm deep they fit into the top of the valves.

got the clearances done with chopper last week
its hard to believe its the same bike
an easy 10-15 bhp and loads more torque
the big thing is how much smoother the power delivery is
so to any lad looking for performance gains
make sure your clearance are to spec
big fair play to chopper
and easy paid

hotboxzerox · #93 12th August 2011, 06:19 PM

looking for
1 x 2.45
2 x 2.50
1 x 2.55

My only other option is to get thicker shims and shave off to the depth I need

Tell me this: I understand a few bikes have used hydraulic cam-followers (e.g. some of the old Magna V4s), thus maintaining (in theory, at least!) a zero-clearance at all times via engine oil trickery. Is the reason these aren't more popular on bikes to do with the high engine speeds? Speak, ye Gods!!

IMO.......
some of the bikes with that sys had probs when the bikes were lying up for a while, oil drained out and starting the bike diddnt automaticly bleed them up again .thus there was expensive work involved stripping off parts to rectify the prob.
iirc the vn1500 needed the motor out to do it and the fuckers shaft drive and all. had to put one of them engines in by meself one time , its not fookin easy .

I see. Not so much to do with revs, then? They might have another go at it one of the days - it seems to work fairly well on modern yokes-with-too-many-wheels.

Hi guys, or probably Chopper, more specifically. Planning on checking/adjusting the valve clearances on my 01 XJR1300 over the weekend and just remembered the book calls for a special tool to hold the followers down. Is there anything else you can use or do I need to get one? Thanks, Mick.

This works on xj750, xjr is only a similar bigger engine
