jsp Posted August 20, 2006 Report Share Posted August 20, 2006 just after a bit of feed back from the 4rt owners out there who are running with the mitani titanium front pipe on, 1. are they worth the money 2. do they really alter the performance of the bike 3. do the alter all the performance right through the revs or is it all bottom end 4. am i better off saving my cash for a reprogramable throttle body whatsit 5.do you need to take out any of the restrictors or has any one tried one of the powercraft ones yet thanks jsp Quote Link to comment Share on other sites More sharing options...
monty-python Posted August 20, 2006 Report Share Posted August 20, 2006 In my humble opinion, 1 yes 2 YES, LESS ENGINE BRAKING AT LOW REVS, FOR ONE, SLIGHT MID RANGE BOOST AS WELL 3. Damn caps lock, er see above 4Havn't tried the throttle body, so, er, pass 5I still have the tail pipe restrictor in place to keep the "bark", bearable, take out the front two. Hope this helps Quote Link to comment Share on other sites More sharing options...
barcota Posted August 22, 2006 Report Share Posted August 22, 2006 I agree with ferretflasher. I have tried most of the accessories for the 4RT and feel that the programmable throttle body is the most worthwhile addition you could make. I have a map that totally transforms the bike into a softer much more controllable power curve that most clubmen would like. PM me if you would like it.

gii Posted August 22, 2006 Report Share Posted August 22, 2006 The availability of the PTB is one of the things that appealed when I bought the bike, but I must confess I find the standard (non programmable) settings very pleasant, very progressive low to medium revs and terrific torque then good power at mid to high rpm. (I have allexhaust restrictors in). Several people have mentioned that this can be further improved at the bottom end but I do wonder, I'd hate to mess about just trying to 'improve' to what I have now. If I buy a PTB does it come mapped as standard so I can then experiment/move from there eg. to Barcota's map, or does it come with some other setting? Does anyone have a 'standard' map to compare with? I think my fear is that occasionally I really need some 'snap' this is generally at a step, I'll approach the step too slowly and mess about until I'm too close. Since I don't use the clutch (one control to many), all I can do when I'm effectively underneath the step is open the throttle and pull back like mad. The GG321's and Sherco 290's managed this fine, as does the standard 4RT. The rest of the time the 1800rpm tickover suits me fine, I just ride the sections with the throttle closed(ish), just have to steer. Still fancy the PTB, just wonder if it'll save me as many marks in the next 18 months as the extra 3 new back tyres it'll cost. Can't see a new header pipe saving many marks. Titanium won't rust though, whereas the standard one certainly does corrode, Anyone know what it's made of? it's not mild steel as it's not magnetic, I'm guessing at some sort of Ferritic stainless?
