Maybe someone has the answer to correct a long cranking but did start after maybe 10 seconds?
Temp was mid 70's, with ATV not run for maybe a month but on battery maintainer with full bat charge noted. The atv started, but then died a couple times after repeated attempts. But when run awhile everything was ok. Although when starting now I do hear the fuel pump humming but seems to take a few ,"long" seconds before full prime pressure.
Is this typical of a failing fuel pump?
I've priced a replacement fuel pump on eBay for less than $40 so am tempted to simply replace it for good PM. Just had all covers off so looks really easy to replace.
Any ideas?

Hi Guys,
We've just removed a Gates belt from a cforce 1000 touring and it looks like an egg shape and we leave it on the side for about 1 week and still didn't got like the normal oval shape, any thoughts on this? Do you think it's normal?

I have replaced the cracked stator cover on my non-running 2006 LT-F400F that I purchased recently, checked all the shafts vs the service manual and pics and advice here. I replaced missing gears, bushings and washers, made sure that truth marks were all aligned properly, that the shift cam springs felt like they returned properly, etc. IAfter installing the new stator cover I checked the transfer lever for proper movement from L-H-R and then cranked it up. Happily, it runs and changes gears well in L, but it will not shift into H or R for anything. I have opened it back up and am going back through it looking for the missing puzzle piece(s) but how can I best check that I have everything right this time before buttoning it back up?

Does anyone know if they're interchangeable? I have a 2002 TRX20TE and 2007 TRX250TE, so getting to a set of common engine parts would be ideal.

The clutch engagement on my 2021 cforce 400s was approx 2700 RPM, very abrupt/not smooth. I obtained a "kit" from RNG consisting of a blue painted spring (spring force unknown) with 12 gram weights, as measured on my postal scale. Installation was easy; 18 mm and 30 mm (not 32 mm as seen on other writings) impact sockets for clutch housing removal. The resultant clutch engagement was still up to approx 2500 and very abupt/not smooth.
The original spring was labeled p/n 0951-1021 (specs for spring force 300/1600) with 18 gram weights.
I called RNG who told me the kit should work fine for my ATV, but that wasn't the case as I found.
The RNG spring was slightly longer than the stock spring, but felt slightly easier at initial downward force but had more resistance than stock as I continued to push down. RNG would not tell me what the spring force was.
I then tested the clutch with the RNG spring and the OEM 18 gram weights with the resultant engagement RPM of about 2050 RPM, a little smoother engagement but still not good.
I am really struggling to get any answers on the best combination of spring / weights to achieve a smooth engagement of maybe 1800 RPM. Note; idle RPM is approx. 1600.
I have searched all the forums and cannot find good information, and RNG appears to be not willing to share information. What gives here? Anyone with experience to share?
