Where did the Shearers go and do you like the CPIs better?

[Cheetah Cylinders, intakes, heads, reeds.]

you will need domes

[Long rod timing?]

+4 is safe. 

[Pipe]

SLP

[slp or pro circuit?]

100% depends on where and how you ride. If your strictly trails or track I’d use SLP. I had PCs on my 4 mil and they pulled real hard in the mid range. I wish I would have kept them. For a do everything pipe I like PCs a lot 

[new engine build advise needed]

Those a great trail pipes. They usually require a bigger pilot jet like. 
Another option is port your cylinders

[new engine build advise needed]

Is your bottom end shot? If not true and weld your stock crank, they’re very stout.

the driveline top end for 800 is unbeatable. You would be at 392 cc with the stock crank.

What pipes and reeds do you have?

[Banshee No start]

And you’ll need gaskets at the reed cages. While your doing that check your reeds, if they’re chipped or showing light through you’ll need new ones.

build or buy a leak down tester.

the jet sizes are written on the bottoms of the jets. So you have stock exhaust pipes?

[Banshee No start]

He’s asking about the tube that connects both carbs. If your missing that it won’t run.

id leak down your motor.

what mods and what size jets?

[is this worth it???]

Banshee prices in Canada has doubled in three years. Personally I wouldn’t because the banshee will be worth more.

[Help with jetting 421 serval]

No expert with those carbs, if your close on the jetting only adjust the slide at this point. That will tell you if your going to need more or less jetting

[Banshee engine rebuild]

Vforce make more power, I’ve heard the Boyensen last longer (have no personal experience)

fmfbpowercores will be great trail pipes, if your building this for open road but a different pipe

[Big bores on oem crank]

Both CP and DriveLine offer a 68 mm bore (392)

CP also has their super cub and super serval in 72 mm for 440 cc

 

true and weld your stock crank

[Help with jetting 421 serval]

What’s it doing?

[A-arm ball joints]

Might be LSR, they usually have a star cut in the a arms.

LSR will sell what you need, basically all a arm makers will sell what you need.

Alba is definitely the cheaper option, you capfuls try saying BansheeHQ member for a discount. Check sponsor list.

i might be interested in those a arms also I’d you do not use them

[Nice clean frame. 2000]

oh how i wish i lived closer. Id snap this up.

[YFZ450R/Redline 421 serval hybrid]

This will be the nicest hybrid yet.

[Banshee engine rebuild]

Bore it again, still life left in the cylinders.

 

for 800 you can get a Driveline set up and be at 392 cc and 70s hp with the right pipes and mods

[Mild rebuild repair 2002 Yamaha banshee]

Should be fine after welding 

[New suspension need wheel suggestions?]

I was just going to say that .

 

Hard to beat CST tires for the price and performance

[Lowering Banshee For Road Use in the UK]

Unless your super broke don’t buy stock shocks 

Any +2 a arm with a shorter shock will work. I’d look at used fox float snowmobile shocks.

for the rear you can have your stock Rear shock cut for lowering.

 

what pipes you running?
