vtr1000 dragbike project

Post by muppet » Wed Sep 14, 2011 6:37 pm

update on budget dragbike project, trying to get the best times without spending loads on engine bits, have jetted the carbs for the open airbox, isolated the carbs from engine heat using a thermal barrier and wrapped the exhaust headers bike has been lowered allround running a locked rear end and 6" over braced swingarm , bracing to swingarm to frame and lose wait by removing items not needed best time so far over 1/4 mile was 11.03 @123mph , with standard carbs/airbox will update on times after next outingImage

It would be quicker with a 1000 engine, though.

It's not falling off, it's an upgrade opportunity.

Re: vtr1000 dragbike project....update

Post by muppet » Fri Nov 11, 2011 11:04 am

updates for next year have started with a lot of weight saving and some tuning bits including....
race light rear subframe. (from bigspanishmarty)
race seat .(from bigspanishmarty)
small 1.5 litre alloy fuel tank.
glassfibre fuel tank cover.
remove one front disc and caliper
solid locked swingarm (removing shock and all heavy linkages)
single reversed cone megaphone with 2.5" inlet 4.5" outlet using enlarged 2 into 1 manifold.
dr honda aluminium velocity stacks, with work done to the airbox ( if it works i will post the mod :shh: )
air shift gear change for full power shifts.
programable shift light.
removed all water cooling ,rads,pipework ,thermostat etc, bit of a gamble but the engine only runs for a short time ie. burnout + 1/4 mile run then return to pits.( less than 4 minutes running time )
Cbr600rr stick coils.
more to follow :thumbup:

i'd be tempted to keep one rad... and/or swap for a (bigger) blackbird oil cooler.

if your terminals are low 120's, bin the fairing too, it won't be doing much at that speed.

for serious weight saving, use late gixxer thou K series wheels, (K7/K8) they're loads lighter.
