Hi,

Just putting my 2003 xb9r cylinder back together and realise I need a piston ring compression tool. Got a feeling this will be expensive from HD so is the any way round it or a cheaper alternative. Manual also mentions the piston support plate. I take it this is used to stabilise the piston and stop is moving, again is this essential?

Also the torque values for the bolt instillation seem low to me between 15-30 NM. My torque wrench does not go down that low and the type of torque wrench I will need to get is more for push bikes!
There is also no mention of lock tight when installing the bolts even though some of them look like they have some on.

Any help advise greatly received

You can use your fingers as piston ring compressors like in the olden days. If you are American, you can put the pistons in the cylinders first then assemble with the gudgeon pin and circlips afterwards.

Ok will give the old fashioned method ago, with ye old fingers. Would I not need another tool to remove the piston?

Thanks for advice

I use a bit of plywood with a cut out to clear the con rod, as a piston support plate. However, not essential as the barrel has a good chamfer.

Ok thanks Adam will bear that in mind if needed.

Ye old finger method is not bearing fruit. Maybe my sausage fingers are the problem.

Anyone have any other thoughts reference my original questions?

I've got this:

Think it is in the Buell manual as an approved tool.

I've never had to use it though.

You can make a ring compressor from thin alloy sheet.
Make a strip that covers the rings on the piston and bent it the radius of the piston with two 90 degree lips for pressing together.

Or insulation tape, the cylinder will peel it off as it goes on.

Easier with your fingers.

I just use my fingers, I guess if you bite your nails it might be a bit more difficult though ;)
