85 mm is 366, I think 83.5 mm is something like 352 or something like that.

 

[Advan]

I think I'll install the 85mm .

 

[Advan]

With the 85mm , would it work a hotcams stage 1 ?

 

[rappy'97]

Advan, can we see some pics of your 350. From the mods you have in your sig, it sounds like it would be really nice.

Ya you can run a stage 1or2 hot cams but don't get past 11:1 compresion because then you need race fuel

Thanks!!

But you have to be careful when ordering a cam ok stage one is build for stock stroke and torque (woods and dunes type rideing) stage 2 is built for stock stroke and horse power (mx type riding) and the stage 3 gose with hotrods stroker crank but most ppl will say that the stage 3 is a stage 2 especialy on ebay so make sure you know which you are ordering before ordering

I run through mud , hills and also in the streets

Then go with a stage 1 I use a stage 1 on mine for the dunes and I can shift up from 3rd to 4th and keep gaining speed all the way to the top till I let off or clear the top

I think you guys are getting confused, neither of the hotrods kits require case mods

Yep you are correct, I could have swore all the strokers needed case work but hotrods is a drop in. Found out that they made the +7mm going off the big bear setup. claimed hp is 32 with stock cam and no porting. only issue is it's a custom piston made by ct and there is only 1 size so every rebuild is a resleeve. but that's not to often

:evilface:So around 40-45. super moded I could dig that :evilface:

 

[hawkster0001]

i think dave had 46 on his 446 with all he had done to it

 

[87warrior917]

Dave76 also BARELY ever rode that beast. So who knows how reliable it is. Like i said these motors can only take so much heat before they start eating bearings

 

[elwood]

i was reading on that other site, a guy went 5 yrs before needing a rebuild running the 446 but I don't know how often he rode it

 

[hawkster0001]

yeah, i woud run both oil cooler setups with seperate coolers if i did somthing like that

 

[duneracerweston]

Oil cooler+ external tank +cv4 trans + synthetic motor oil + exhaust wrap + air ducts=one cool warrior

 

[87warrior917]

I need to make mine some air ducts. So have you tested the new oil tank duneracer?

 

[beastlywarrior228]

i guess well soon find out how reliable the 446 is with someone who really rides it:evilface:
