i bought my zilla a month ago. it has a pipe and muffler fmf gold searies. k&n air filter.no lid on the air box. my friends banshee spanked me by 5 to 6 bikes. he has t5s k&n air filters and a 4 deg timing key . my plug looks good not fat or lean.he just walked away from me with no problem i dont think he is makeing over 50 hp aney ideas.need to put him in his place.

 

Maybe your zilla is due for a rebuild.

 

You should be bustin' his a@@ on takeoff. I don't know about the T-5s on topend, though. If you're not having to hold on with both hands then something is wrong. Do a leakdown test. I had some bad crank seals and bearings a while back and this made my Zilla slow. I've got the Gold Series pipe and like it. Noone has ever beaten me even with the bad seals /bearings, so have it checked out.

 

I've never even heard of a slow zilla in my life!!!!!!![img]i/expressions/face-icon-small-shocked.gif[/img]

 

If the banshee is beating you, something is deff. wrong unless he has put lots and lots of money into his, and your stock. (ex. the pipe)

My stock Zilla absolutely killed a stock (I think!!) Banshee up comp hill at Glam, and a mild-moderate modded shee hung wheel to wheel, with my zilla pulling maybe a tire length on him by the top of the hill depending on my/his start.

I had a crack in my intake carb boot that made the quad slow...go figure!!!

87 zilla FMF gold series pipe with turbine core silencer K&N filter (no lid)

 

Is the elevation a lot different from where you live to where the bike came from?
How much compression do you have?

 

Never thought I'd hear the words slow and zilla in the same sentence!

 

sounds weird. Hope the quad gets better so you can restore some "ZukiPride"
