Had a quick look at Dallas's bike earlier today, he had taken the plugs out for a compression test and found the front plug was very much of the white insulator variaty, so looks to be running rather week still, dispite being on its 2nd set of injectors and 3rd ECU already this season

Ran the compression check and came out with about 120psi on each cylinder using the tester I bought 30 years ago
I then ran a leak down test on both cylinders and both cylinders were very good, loosing a couple of % at most

Had a look at the cambelts and timing marks, all lined up ok but the front cylinder belt was extra slack going on the allen key method between the roller and the belt I could have easily fitted a 10mm allen key if not a 12mm one, so retensioned the belt for him

Still a lot to do over the next few weeks but hoping to get it up from its 54 ish bhp back nearer to the 64 ish it started the season with, then hopefully he will be able to mix it with Neil, Andy C and Matt
That is Providing its dry and he gets out and does some quallifying so that he doesn't have to start from the back of the grid

Don't know if it helps Kev but the rear cylinder on mine always seems to run hotter than the front . Thats with either the brown or white injectors (to be honest the white injectors made no difference at all) and a different ECU. The ventilation is I think is as good as the front even more so now without the airbox. Go figure eh.

Speak to Angry about it as well cos at Pembrey he had a temp sensor directly onto the rear cylinder.

That's why I ran an offset map with a slightly richer mixture to compensate for the rear cylinder being hotter. It's a well-known ducati thang.

Still only made 59bhp though!

I always ran cold air ducts to the rear cylinder.

Wasn't that to keep the 800 pot cool?









PS For the avoidance of doubt given other recent threads I AM ONLY JOKING. Chaz is a top bloke who put good riders on well put together bikes*, and also provided good food and company through the years. (Are you still coming to Cadwell so I can bring the cheese and wine?)

* PPS they were ok until their new owners kept binning them
