Any 998 owners? maybe you can help UPDATES NOV 4 2011

The exhausts for a deep sump will work on shallow sump motors (998's) but not vice-versa

Everything ive read on doing this required some custom work. Cutting the pipes, and part of the fairing. the 50 mm full system for the 998r (deep) is not quite a direct fit on the US 998 (shallow) as far as i know. I still havent checked out the info that JV gave me but i will tonight.

Do you have any info to back up your claim....? Have you or someone you know done it?

The "R" is the "large testastretta" setup - cyl stud spacing is different I believe and that may affect the port placement, not sure at all. Wouldn't be very difficult or expensive to have a muffler shop get it 'right' for you I wouldn't think though.

JV what say you on high comp pistons? No way they will run on 92 pump gas right?

[junior varsity]

i think that is largely dependent on tune in addition to what compression ratio your pistons turn out to be.

848evo has 13.2:1 compression from the factory.

Had a Termi 54mm deep sump system on my Blondie- seen in my avatar- (unfortunately sold her). The difference is in the bends from the horizontal cylinder to go around the sump extension.... which is not an issue if you have a shallow sump Testa motor. I have no idea why someone would have to trim/cut the actual exhaust... I just had to trim the bottom of my fairing a tad which was no biggie

I have 54mm Arrows on my SPS and had to trim/clearance the rear of my fairing a tad also

right on,

i found out today that i have the 45mm slip ons..... now im torn if i should try to get a DP spec ecu with new intake for the 45mm or replace it with a full system 50mm.

so after reading into all of this more, wheels wheels wheels

yes. if it doesn't break the bank - bst's or forged magnesium

yea they are not cheap but in my situation i think it is money better spent.

[junior varsity]

The difference is substantial - much more than I expected. Its not about "can you flop the bike over for this turn" but rather "well, now that I'm leaned way the hell over, perhaps a scoootch that way would have been even better"

I need wheels and a slipper clutch IMMEDIATELY! Thats what im spending some cash on.

ok guys so i sent some emails about some used wheels. we will see who responds....

Now im looking at drop in slipper clutches in the 600 range. Motowheels and ducabike make a drop in. One is a 5 spring and the other a 6. Whats your take on these things?
