Wrapping the pipe with some bacon might be a good smell as well? You now have 694.6 cc of fun.....and a bunch more compression. So I can safely paint 700 on the side now?

A huge difference in power Shocked

I will run a number of test when engine is broken in. Only managed 100km so far. Embarrassed

There is definitely more than 50cc increase in power.High comp piston is the culprit I think.
Sounds great too. Real deep thump now. Opening the exhaust helped.
Still running stock carb with oversize jets. Will install Flat side when $$$ are more available. Wink

So far Temp is about same, maybe a degree or 2 higher.

Clutch issues are back. Sad

Replaced clutch a couple of months ago with 10% heavier duty springs, and now because of my new found HP the bloody thing slips a little when cold. Sad

Now I still havent opened the throttle yet as I have only done 150km so far Embarrassed

I know terrible I should have clocked up heaps more by now. Embarrassed

How can I beef up a already beefed clutch so it can handle the extra horses. and I mean Horses Cheesy

The first thing to do would be to check the operation of the clutch rod and lever at the engine. Make sure there is some free play and that the clutch lever/rod is not applying pressure that prevents the clutch from fully seating.

If that is OK.....then take the clutch apart and clean everything with a good solvent. When the plates are dry, lay sandpaper on a flat surface and lightly scuff the fiber plates until the shine is gone. Do the same with the metal plates - but only enough that you have a scratchy appearance. Clean the plates again - and them dry them off and install them, and add some oil to the surface as you assemble them. When it is all together make sure you have the proper operation of the clutch rod, and that the rod is not putting pressure on the clutch and keeping it from seating completely.

Your clutch can handle the power - if it is working properly and not contaminated with friction modifiers from using the wrong oil.

Here is a long thread that discusses most of the clutch slippage issues.

I have been very careful of the oil I use. There is plenty of free play at the clutch lever. Slips in top when i roll on the throttle from 100kmh up. It was fine with the stock piston.

I sure hate to hear its got stouter springs, That "paddle" in the clutch throwout, you know, the one that actually pushes in on the rod that goes down inside the clutch pack, is a known issue. Caused some problems for me when it broke. Busted the cam chain tensioner, the one the adjuster bolts to. Did a coupla other things, minor stuff, but it was at low speed & just off idle when it happened. It brought the bike to a halt. I had shimmed the springs. I doubt seriously I had anywhere near a 10% increase with that little bit of shim., If I was gonna do that Id take one to a machine shop & have one built out of billet stock. I kinda think these things are like pressed into shape, Im wanting to say Sintered,, anyhow, we have seen a few failures in there, not tons, but a few,.
