NO gap means missing spec in manual or eyes looked at valve gaps and see none?
?????????????
It has HLA (Hydraulic Lifters) or solid tappets.
Get the service manual and see?
And some information from me! Larry was always economical with words, failing eyesight.
Hi,
Your clutch would usually be the issue. But your ATV has automatic clutch so we can disregard that.. I will get that you need to alter your final drive (ie check 2wd, awd etcc).
The problem could also be belt related, so you might want to check the status of the belt. If you need more help, you can also call Polaris at 1 (800) 765-274.
Thank you.
The ATV needs maintenance. If you have done the standard maintenance for the number of hours of use, then the maintenance counter should be reset. This may depend on the model of your ATV, check your documentation. For an example, see the manual for the 700 Honda ATV: https://cdn.powersports.honda.com/documentum/MWOM/ml.remawmom.2016_31hl3620_sxs700m2_m4.pdf . Page 14 shows the maintenance minder light and the reset for this model. Page 93 starts the section on the needed maintenance. On this ATV, there are three slightly different maintenance routines. One is the initial maintenance (20 hours) then two routine lifetime that will alternate over the use of the ATV.
I hope this helps.
