Smooth after roller upgrade

Just managed a test run after roller install. Temp was only 10c but dry two verical strips of duct tape on the front of the cooler to get the temp up and of we go.
Mark you have surpassed yourself the roller map is so smooth and fuel consumption is better going by the dash. WOT roll on in top from around 85 MPH and you are at 124 in an instant no holes or dips just buttery smooth power, it’s going to be harder to keep my licence.
The one thing I found when doing the cam upgrade was that these bolts were not very tight.

I had the cam boxes on the bench, I had braced myself to undo them and nearly went arse over tit because they were not tight.
Maybe this also contributed to my vibration but it is all gone now thanks to Mark and maybe these bolts being torqued.
Also it is so quiet now. Tappet check tomorrow then wait on some decent weather, that could be a while though weekend temps are forecast to be 1c at 15.00.

Sounds great! Glad all has gone to plan. And well done to MR Beetle too by the sound of it.

Great to hear you got it sorted little 750 by the way do you (or anyone else) know if the replacement roller kits b, c, etc are a fit for all the 8v engines, In other words will a b kit for a Stelvio fit a GRiSO that needs a b kit or are the cam profiles different?  I was looking at a b kit on TLM website, part number kit B 1A002063 which is the number that I had got to match my 2011 GRiSO here in the Ghetto.

But on the TLM site, it is advertised as a Stelvio part! I want to be sure that it is the correct one before I press the BUY button which will be early in the new year.

Thanks in advance for any input.

Same kits for Stelvio and GRiSO.

In all of the kits the major componentry, ie the cambox assemblies which are complete, rocker carrier/cam and assorted fitting paraphernalia, tappets etc, are the same. I haven't checked numbers but I think that probably the roller cam is universal to all models including the 1400.

What differentiates the kits is the other parts in them. Bikes that require 'C' or 'D' kits need to have their heads removed to shim the inlet valve springs so head, inlet and exhaust gaskets are included along with the shims and valve guide oil seals. 'A' and 'B' kit engines do not require the shims so those parts are missing from the kits.

Just rode this morning after a valve adjustment and map upload. Low speed handling is excellent, the dead spot at 2500 rpms is gone. Its a real pleasure to ride around town now. Looking forward to highway rides. Great work!

The latest roller maps seem to be even more refined than the last of the flatties. I've had two Termi equipped rollerisations through in the last month and have uploaded the Termi map and it's great. The Mistral Hi Pipe with dbk map I'm running with my *New* roller motor is superb and better yet than the Termi bikes but we've covered the *Why* of that many times so I won't bang on.

Have you blokes who have rollerised or have factory roller engines noticed the distinctive, what I call 'Whickering' noise the rollers make? Thinking about it it's completely understandable but it's a real individual, stand out, noise. I like it. Far better than the 'Two cheesegraters fornicating in an iron tank' noise of my very early A5 motor with flatties! It was awful! Everything about it said "Not Good" but it worked brilliantly for 90,000 kms! Go figure!

I cant believe how quiet mine is when warm, by whickering do you mean like the rollers spinning speed changes as they ride the cams type noise if so then yes.

I've noticed it on the Stelvio and the GRiSO. Kind of a cyclical whir. I like it. Definitely a better sound than the "loose nuts and bolts in the washing machine" sound it used to have.
