Ah right. No, I didn't realise that the Athena kit used an O Ring for the above and consequently it leaked coolant

I though you had an oring conversion on your kit?
I didn’t know that they all used gaskets , doh!wrote on 31 Oct 2023, 18:53 last edited byI’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...

Might have to upjet in this weather mate, my French import bike loved to run on 210 in summer and 22.5 pilot when winter came, didn’t like it at nightime I had to go up one jet on each

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…

I believe it’s 55mm x 15mm but am not 100% sure…

That sounds probable. Same size piston but with a longer stroke to take it up to the 200cc

I’m getting conflicting information from the web about them…If anyone has an old spare unused one, please sell it to me or at least measure the thing! Please!
I’m guessing that the diameter is the same as the standard pin if it uses standard small end bearings? Just the length would be different?
I don’t have the tools to measure the pistons interior myself… -

I don't have the possibility to measure, but the diameter of the 170 pin is the same as stock, but it's longer. It's also lightened with a conical bore, so thinner walls towards the ends. I would not recommend a stock needle bearing with the 170-kit, there will be too much axial play on the bearing, so it can wander out of position. I had a lot of trouble finding a suitable needle bearing for mine.

@Rallyfinnen
@SpookDog Small end bearing from the YFS200 Blaster is the proper one,fits like a glove. I have it on mine.
The stock has too much play on the 170kit,as mentioned above. -
Hi bud
Send me your address in messages and I’ll send it out! Sorry I completely forgot to busy ripping on my dt

…Cheers for the info guys, will try and measure the gap in the inside of the piston for the little end bearing width…
The roads we’re actually dry today. My bike actually felt like it was revving and pulling properly for the first time since it started pissing down with rain every day!…
nice!… -

No expert in bearings, but are they not usually having rather standard measurements? Such as "Ø20 mm inside, Ø30 mm outside, 20 mm wide" and then graded by various tolerance requirements?
If so - why do everybody post like "you need the bearing from a 1989 model XYZ345" instead of "SKF #7709 or equivalent from any of a dozen manufacturers"? Not sniping at Rallyfinnen here, it is a general observation from way back.
I mean, these guys have thousands of sizes and models on the shelves that I can obtain within a week from local suppliers. That would be far easier than trying to track down a certain model built a certain year in a certain region.
https://catalog.skfusa.com/data/bbm19enu/011/html/export/SKF Bearings and Mounted Products.pdf
That's 579 pages of normal bearings, there are droves of specials as well.
