DRZ400E 2010 street legal gutless

**dmoo1790** · 6th February 2010, 11:34

I picked up a new DRZ400E street legal on Tuesday. It feels gutless under load and/or anything more than about 1/3 throttle. Took it back to the shop and they said "that will be the card restrictor". So I said remove it and they said they did when I left the bike with them on Friday. But today it doesn't feel any better. Still won't hold revs on a hill, surges when I try to open the throttle and even stops accelerating on downhills. Anybody had a similar problem? I suspect it's running extremely lean on main jet.

I've ridden a road legal E and it did'nt feel like that at all. I owned a off road only DRZ and that was great.

Welcome to KB. Have you ridden one before buying it? Is it maybe just a drop in performance coming from the big litre bike?

Could be something to consider...what's it geared at and what carb is it running? My rd legal E kicked arse...for a 400.

Thanks for the feedback folks. Yes, I will be heading back to the shop (again!) on Monday morning.

Hi Padmei, No I hadn't ridden the 400 before but I have recently ridden a DR200 and DR650. I swear my bike feels closer to the 200 than the 650 and that can't be right. In fact the 200 carburetted better but just didn't have much grunt which is acceptable because it's only a 200. The 400 should feel much stronger than the 200 but it doesn't.

sounds like a dog mate, hope they sort it quick smart for you

Turns out there was a huge bit of rubber blocking about 80% of the intake manifold. (I would post a pic if I could figure out how to insert a jpg.) This is put in so the bike can pass Australian ADR noise rules. There are actually two restrictors. The first one, which was removed on Friday, just limits the throttle opening. (No wonder it didn't feel any better after removal!) The second is the intake rubber. I don't know why the mechanic didn't tell me about the rubber on Friday. All he keeps saying is that Suzuki don't want the restrictors removed until first service. The sales guy rang Suzuki to check if it was OK to remove the intake restrictor and they said yes. Usual large corporate bad communication I guess. I will be writing to Suzuki to complain and tell them that the restricted bike is downright dangerous in traffic it's so slow.

OK, I figured out how to attach the pic.

sorted, how she feeling now dude, bet the fronts pointing skyward often.

thats a pretty heavy handed restriction, the ockers must have some pretty hardcore restrictions

**Padmei** · 8th February 2010, 18:27

Is it going alright now? Does the carb need altering?

**offrd** · 8th February 2010, 18:35

Wow! That is crazy!

That is half a Chinese car!

For some reason Suzuki do this with some of the models and even back in 1998 when I bought a DR250R it was like that and you have to slice it out with a model knife. The other thing is you do have to run them in a bit as all the bikes I've bought aren't flash straight out the shop, they do take a few kms to loosen up. As in how many kms have you done so far?
