what mod should i do next!

[quickbansheeman]

i have an 05 banshee with t-5 pipes, v-force 3 reeds, boost bottle,k&n filters with 310 main jet, and my cylinders are bored out to the next size. i have a 110 compression. i usually go to pismo and i kinda want a little more power what would you recommend? im really confused in what to do next!

[joneser4u]

bigger carbs and an adjustable timing plate or flywheel key and maybe a koolhead with some smaller domes to raise that compression.Then you can start on internals!

[fastbanshee8]

Get rid of the boost bottle, and put the tube back in the intakes, because the boost bottle will eventually end up cracking your intake boots, causing an air leak. Get it ported, when you do your next top-end rebuild. It doesn't look like a top-end rebuild is very far away, since your compression is at 110. Once it drops to 100 or less, it's rebuild time.

At 110 compression, as said...pull the top end, get the cylinders fresh...and ported. Most builders like to port the cylinders then bore them, in case they have an oops and mark the cylinder...

Now is the time to do it and do it right!!

More compression, advance the timing.

adj. timing, cool head with 19cc or 18cc domes, depending on what you wanna run fuel wise and what your final compression will come out to..get the top end re done with a nice port, dyna fs ignition nology hot wires, stroke the crank, cheetah cylinders, 35mm carbs

if i put a cool head with 19cc domes would i have to adjust the carbs? i think that might be my next move!

No, you should not have to rejet, for a new head. Putting the 19cc domes in the cool head will raise your compression, but it won't hide the fact, that the motor is due for a top-end rebuild. Raising the compression with a smaller dome, is just a band-aid solution for your low compression. You should port it, and do a top-end rebuild at the same time, so your motor is in good shape. That is the best way to get the most out of the mods.

The guy said its been bored over once. To me that tells me its more than likely recently been rebuilt, or he knows the condition the top end is in and doesn't seem too concerned about it. I am more apt to guess he doesn't know how to properly check compression, or he has a shitty compression tester.

I know that, but he didn't say if it was done recently, or not. Hell, the top-end rebuild could be a year old, or better. The reason I replied like I did, was because we've had numerous people on here, try to put a cool head on, with smaller domes, to try and fix their compression problems.

[quickbansheeman]

i know how to check the compression, well i have about 8-9 rides on my bike, and its about 6months old. what size domes would you guys recommend? im kinda trying to avoid redoing the top end, im on a $250.00 budget.

I recommend a head. What compression tester do you have?

[quickbansheeman]

my friend has a snap-on compression tester!

[Snopczynski]

yeah, it may actually be low then. Where is your squish at?

[quickbansheeman]

squish?
