416 Kits!!!

[BassGin3]

I want to get a 416 kit for my EX but didn't know where to start or what to get. I have a Big Gun full race exhaust, K&N filter, and it's jetted. I was thinking of just a 11.0 or 10.8 comp. piston. I wanna be able to run 93 octane. Also thinking of which cam to get between hotcams stage 2 and is an HRC cam really worth that much more??? I don't plan on spending too much on the kit but would rather spend just a little more on a better piston or cam and have a little more reliability.

I just got a JE 416 10.8:1 Piston, Cometic Flex Steel Gaskets, Valve Seals, and TC XC Cam put in! I think it will be a great setup. Get the 10.8:1 for pump gas. Haven't heard anything bad about the HRC, or the TC Cam like I have!

I have the hotcams stage 2, and I love it. Never had any problems with it. It made a huge mid range/top end difference. I have had this setup for over a year and no problems. I run 93 octane gas.

if you want it done right you can beat his quality of work to price ratio!

[Dave400ex]

TC XC Cam is $190 plus shipping and there is a core charge, just send your stocker in!

that cam is $190 plus you need to give them your stock cam??

if you want something cheap and reliable i would just order the stuff from C&D. i would get a 10.8:1 piston and a hotcam. the hotcams only run about $125. i am running one without any problems. i can't see paying the extra cash for the hrc. yes, it comes with the decompression assembly but you don't need that. i think you are just paying extra because it is a honda part. it is a pretty similar grind as the hotcam anyways. the piston will be around $120. the cosmetic flexsteel gasket kit is $40. the boring will depend on who you have do it. i paid $90 for boring and having them put the rings on. i told them to gap the rings but who knows if they did or not. this is about all you need. a service manual is about manditory if you want to do this work yourself. i found it to be easy with the manual though. good luck

im wanting to get my engine wroked on by a pro so it will be right on and make the most power with keeping relibilty in mind. Where should i send it to? i know of Ct,Hetrick,FDO (cant find website) thats about all i know that does engien work. can someone tell me somewhere good for power and relibiltiy.

[Dave400ex]

Heard a lot of good things about GT Thunder, FDO, Baldwin, and even Fischer's Cycle can build a great motor! All from Ohio also.

what is fdo's webstite?

[Dave400ex]

FDO does not have a website. Give them a call!

for the moment i'm running a 406 bore-but i have an xr400 cam with an 11:1 comp ratio, dragging a yfz it'll stay up with it until the last seconds of 3rd gear

[BassGin3]

how much does it cost to ship u'r engine out to get it bored and possibly the piston installed?

[Dave400ex]

I would just have a local shop do that. No need to send the engine unless there is nobody local.

[Hotdog]

do you need harden rockers for the TC cam?

[Dave400ex]

Nope, the TC Cam is a drop-in. I went ahead and bought new stock valve springs and rockers though!

[BassGin3]

Do you think getting just a cam could make a big difference with a full exhaust, air filter and proper jetting? If so, how hard is it to install? Does the bike need to be re-timed or anything?

[Mofo Racing]

when you bore your motor to a 416, do you bore the sleeve and put the piston in. I thought that there was a coating on the sleeve that had to be there.

[NTPracing22]

yeah all you do it bore it and put the bigger piston on the crank shaft. (in lamest terms)

[BassGin3]

What's the measurement of a 416 bore? Stock is a 85 mm, correct?

[Dave400ex]

416 is an 87mm piston.

[BIGRED400]

When you do it coat it with this she rev's quick and the heat is held away from the piston making it last longer;)

im running a weisco 11;1 comp, with a hotcams stage one, dynojet 170main 38piolt, with rev box, and k&n breather, and outerwear, custom airlid, and white bros. full sytem E-series, port and polish, 14 tooth renthal sprocket, and bars, Rad designs Carrier with Holeshot 22" XCTs in the rear and 23" up front!

[BassGin3]

Anyone know of a good shop around Northeast Mass. that could do the machine work?

[BassGin3]

another quick question, anyone know how much power a descent 416 kit puts out? Just curious to see what kind of improvement I might see over stock.

[tnine416]

it depends on how extensive your motor is. I would say with a bore, piston, cam, exhaust, and fcr properly jetted it would be around 35hp or more:eek2:
