New gears

I finally got the new SSF pyörä gears with no syncros. Looks pretty cool but hopefully this is the last time I see them. I gave them to Alhomatic's gentle care and I wish soon have a fresh 091 in the garage. Ratios are 3.4 - 2.0 - 1.5 - 1.15 and final drive 4.57. Differential is Peloquin torsen type locking unit.

Head job pt.2

Nothing beats a good head job and this time it really was worth it. Flow was improved 10% all across the range and even more with the manifolds.

Xceldyne titanium valves this time. 49.6mm intake and 38.6mm exhaust

Before and after(yellow)

After an hour with flap sander everything fits like they should.

Interference issues

88mm crank and roller cam with quite big base circle didn't just drop right in.

Pieces of the puzzle

New plans

It's time for winter overhaul again. It's a pity I did not get to see the full potential of the old engine due to small setbacks, but it's time to move on. New engine will be 88x101.6 and quite a lot of parts will change. Let's see what we can build out of these.

Time for good old out and in again

It didn't take long this time. KEP Stage 2 clutch just didn't hold, it started to slip already on 2nd gear. Strange, since it was exactly the same clutch I used last year and it did hold. There can not be so much more power, or can there? There was no point in burning the disc also so it was time to pull out the engine and upgrade the clutch to KEP Stage 3.

Small burn marks on the old clutch, driven ca. 100km.

And while I was down there I also installed the incredible Marco Mansi special IRS bolts which allows rear camper adjustment.

Done. I hope this was the last time this year for this.

Oh yes, and my new launch control is working perfectly. I'm using two line locks, one for the front brakes and one for the clutch. I can release the clutch with a button on the steering wheel and at the same time release front brakes and RPM limit.
