416 questions

[bcg717]

I want to be a little bit faster so i guess its time to upgrade a little. To go to a 416 what else should be done to be reliable. example Stage 2 Hotcam.. I ride mainly xc. Is their diff. compressions for this kit, if so which do you prefer and why, and what gas would you then use. Any brand better /more reliable than the other. I know its going to be as reliable as the install. Also, is this something that can be done without taking it somewhere if i'm decent with a wrench. And last, are there big differences between 408-416-426. What would you prefer? Thanks in advance

Talk to Colby at C&D, he can get ya all you need.

At a minimum I'd do a 10.8:1 with the stage two.

JE, Ross, and Wiseco are all good pistions

Extra items I'd add for reliability:
CRF cam chain
HD head studs
8-plate clutch kit
New Viton valve seals

I have a 416 now and love it. There isnt much difference in the three you listed. I am running the stage 2 hotcam and it performs great. I prefer JE or CP, but i have also used wiseco and they are great too. The most compression you can run with pump gas is 11:1. I have the sparks 12.5:1 and notice a little more torque than the 11:1, but not a whole lot. Hope this helps. If you need some more help with it let me know. Ive been running a 416 for 4 years now.

Did you change anything besides going to the stage 2

How much does it cost to get that installed? bcg717 did you pay to have that done? How big of improvement was it, how did it do with the *** dyno.

Not sure what you are asking. sorry

[bcg717]

I was just wondering if you also did this.
CRF cam chain
HD head studs
8-plate clutch kit
New Viton valve seals

[drew416ex]

I havent done the crf chain, but probably will on my next rebuild. I do have HD studs. I am in the process of putting in a gt thunder 8plate clutch but i have been running the stock with ebc plates and hd springs for 2 or 3 years and havnt had any problems. And the only valve seals i have ever used were the oem valve seals.

i have a je 416 with the 10.8 to 1 with the crf cam chain and a stag 2 cam. i also have a 450r carb. it runs really well and i have never had any problums with my ebc clutch with the hd springs. i did pull a head stud though so i would take the cylinder to a machine shop and have them put in the bigger head studds. also i have the stock valves and springs but i plan on geting after market. not that i think that i need them but it is most likly a good idea
