So Close!...

I must admit, I have really changed my tune with the 170 kit.
What I would say is, make sure the powervalve is ported flush. Genuinly mine protruded the exhaust port stock. So benefits from modding the valve even if you leave the exhaust port alone.
I think the DTR is a better choice for the 170. Just because you're more likely to be utilising the benefit from the bottom end more due to the nature of the bike.
TZR is more of an open stretch bike where you'll want more HP up the top end.

I’ve been getting a niggle the last few days. When I fitted a new pilot jet a month or three ago the rev pickup was so much improved that my little bike was actually popping unintentional little wheelies when I was pulling away, even cold. Just lately it’s been getting unresponsive, you can hear the ‘bore noise’ from the carb without the engine picking up. If that makes sense?
Any ideas wtf it’s caused by?
I’ve been getting crap in the carb problems forever, usually it’s the pilot that gets affected. Does this sound like main jet obstruction?Any help, Yada ~ yada…

My Cagiva is running like shit at the moment.
Built that engine the summer and it was legit rapid. Went to Belgium a few weeks ago and come back and the bike ran so bad. Spent the last two weekends jetting it. It can't be the fuel since that's the same before I went to Belgium, however the temperature has dropped...

It’s a weird one! I cleaned the carb out again. Another tiny little bead of shitty/water in the bottom of the bowl. Not even half a match head. Less than usual.
This time I junked the air filter because it was starting to disintegrate. I thought I had a good NOS one but that was crumbling as well! It’s definitely running and picking up a lot better without the old filter. Seems it’s down to the fact that it really doesn’t like the damp atmosphere this weather is making. Way too humid…
Too much rain! I didn’t even consider a low pressure atmosphere!…It used to really love the cool dry early 5o’clock morning air a few months ago! You could really feel the extra whump to each charge of mixture. Especially at low rpms…
