Sorry yes

It’s you’re cam angle. Can’t handle lower temps and sticky snow Put a 46/42 cam in with a 140/220 and you’ll be fine I’m sure

Looks good

Looks like you need to go over all wiring and inspect Clean clean clean Take apart clutches and inspect Check bearings Chaincase

The primary will always be a little hotter then secondary. The key is to get them close and warm to the touch, not burn you’re finger hot. Stiff springs up top tend to run clutches hotter. I try to run the heaviest weight with lightest springs

Bigger lug needs a little bit lower gear ratio and cam angle to be happy all around riding in my opinion

Get yourself a $20 inferred thermometer. Point at primary and secondary after a good wfo run to see difference between the two . You should be able to put you’re hand on primary and not burn you’re finger immediately

Being inventive like that is awesome Looks like it will work well Good job

The stm weights are aggressive and looks like you’re last cam angle is a bit too. Go with what doc and chief said on last cam angle and try . Rpms will definitely come up just by that change alone. But , the stm weights are aggressive and might need to be lightened up too ?

Try 68’s What elevation are you and track lug height?

Must have added fuel down low as I said it’s very lean at idle, especially with some tunes.

The bigger lug will have more resistance I’d lighten weights with current set up and get a shallower start cam like a 46/42 full progressive Or keep everything the same and gear it to 1.81 gear ratio. Try these Might wanna invest in set screw adjustable weights too

Reeds? Timing? Bump it up to 1850 and try It’s usually lean down at idle and adding 5% fuel (pcv)in zero percent column from 0 to 2250 rpm helps sometimes ?

I have jobs in toronto but live over an hour west. Can’t you go to a dealer and borrow or check?

I totally get what you’re saying bud. I don’t just go by rate on a spring though. For instance? It can have a high rate but belt slips down in secondary cuz of hole shot with a great studded track. Like a 120/240 has a high rate , but the 120 at start may let the belt slip down in secondary...

Google polaris browse for part numbers As lid said. Be careful installing. I made a puller years ago for these bushings . Polaris dealers have the tool too.

As long as it’s the same compression height and dome shape then yes
