Next mods> Cam etc...

[casey_lamm]

Need some help deciding what I want to do during this time when I cant get home to ride much.


I have a 07.

My mods are HMF slip on, K&N, Dynojets

Im now going to get into the engine a little...i don't think I want to change the cylinder..


I want i little more snappy response...

Considering hot cams stage 1 or 2...

anything else you can think of I should consider.

also would you go with stage 1 or 2...

If you don't want to go too crazy, how about an XR400R head gasket (thinner, gives a little higher compression ratio), a HotCams stage 1 cam, and rejet? You'd be in it a whopping $150, and you'd see some decent gains.

dont want to go too crazy but want to do a little more then just the cam....


I got about 500.00 to spend give or take

Higher compression piston. Just need to hone the cylinder for the new rings.

I agree with Joex on the drop in piston. Do a light hone and a stock bore piston and a stage 1 cam. It will really wake up for less than 300 bucks. Id open the air box also at that point.

[casey_lamm]

if im doing that you wouldn't go ahead and drop another cylinder in? oh...on the stock bore pistons where should I go to get them? any brands have a solid track record.

hone is when they make the cross hatch on the cylinder walls correct? Do you have to do that when you get a new piston and rings? I say get a higher compression piston and the hotcam stage 1. Piston gives quicker revs and a little HP/throttle response increase and the cam will give you all around more power

Yes and Yes

[casey_lamm]

not sure, i will learn with you :)

so far it sounds like all that is affordable and within budget...


I will have to pay someone to do the hone...so if that work is going to be that expensive I might wait and do some more.

I will probably do the stage 1 hc, and the piston...


since im doing all that is there anything else I should order and put in at the same time...


simple mods...or preventative wise?

prior to boring out my forst 400 i went with a 450r carb. stage 1 cam. exhaust and air box eliminator kit off ebay. and it made quite a bit of useable power. in fact the carb upgrade i think was the best bang for the buck. my friends had bored bikes with stock carbs and couldnt hang. i only bought all that prior to the big bore because i knew it would give me some gains as i waited for the dough to p&p and do a big bore. and boy did they

Honing should be fairly inexpensive.

HD studs may be a good idea but you're getting into a few dollars, nothing outrageous though. I can't give an $ estimate.

what about a curtis sparks andvanced timing key. 20 bucks and from what i hear WELL worth the buy.

[casey_lamm]

i could do that but dont really understand what they are for and how they work.

Ill have to read some stuff on it.
