How radical is the porting compared to standard? I'm guessing you can specify what type of tune you want, or is it like the old Stan Stevens stage 1, 2, 3 system?

[andrewj1680]

I'm normally asked what I want from the bike so I'm guessing he will time it to meet your needs, I don't hang around and don't like to sit in traffic so I just tell him to go all out with it

[Nottsbiker]

Will be interested to hear how it rides on the road when built up.

Can't beat a healthy two stroke on the road

[andrewj1680]

My dtr pulls hard all the way to red line with the cylinder and head he did for that, it used to drop off top end however it doesn't anymore, imo it's worth the money

[Calum]

@nottsbiker Yeah it's not really stage this stage that.

It's more, I run the bike 10K plus and thus the porting should accomodate this, I.E. very late port timings causing lots of lost air and fuel below peak power, or I want punchy mid range, which would tell him how it should be ported.

[Nottsbiker]

I think I'd go for mid range as most of my riding is around the city centre and quick get aways with an easy wheelie or two is ideal for me

[andrewj1680]

@nottsbiker mine is ported for top end but will still come up on the back wheel in 3rd

[Nottsbiker]

Glad to hear

[andrewj1680]

Well that's the pic update out the question lol loads of nice fresh red bits frame, rear shock spring, radiator mounts,headlight bracket, rear peg mounts and rear grab handle all done Rosso red

[ricky0115]

@andrewj1680 did you have to remove the spring for painting?

[Calum]

@ricky0115 Yeah but it's not a hard job to do

[ricky0115]

@calum I am a total novice to motorcycles, normally I don’t venture past building my brothers pushbike at Xmas

[Calum]

@ricky0115 You basically compress the spring. which allows you to remove the retaining washer. It then just slides off.

[ricky0115]

@calum oh I think I will leave it, a friend of mine did that and ended up with a broken chin and dentures. Saying that it was a car shock so much more powerful I guess you could probably compress the DT spring with your hands

[finnerz89]

@ricky0115 not likely, still requires a lot of force

[andrewj1680]

I compressed it by hand so there isn't a lot of tension on the really and I'm running the dt200wr rear shock setup so it's possibly easier to do giving that you can turn the stiffness to suit

[alex_dt]

I wonder what is the Mick's philosophy behind cutting WR200 head to DT200R chamber design ? Like it's a a tune for the mid-range ..

[andrewj1680]

I don't know alot about it but I do know it totally changed my 125 which is why I gave him the 200 as I know he seems to know his stuff he seems to be pulling good power figures to anything he puts his hands too

[andrewj1680]

 nice and clean
