Carb or FI or New Bike??

Bike India - - TECHNOMAIL -

I own a Yamaha FZ and I have been quite happy with it for the past few years. I am on the verge of in­vest­ing in an­other motorcycle. Be­fore zon­ing in on a new ma­chine, I want to know if it is pos­si­ble to equip the motorcycle with a fuel-in­jec­tion sys­tem. If yes, will it have any ad­verse ef­fects on the motorcycle?

Brinda Ra­jput, Mad­hya Pradesh

Dear Brinda, it is pos­si­ble to con­vert your car­bu­ret­ted Yamaha FZ to a fuel-in­jected one. How­ever, it is not re­ally an easy process be­cause you would need to find the right tech­ni­cian who can carry out such a pro­ce­dure with­out dam­ag­ing the sys­tem. So we don’t re­ally rec­om­mend you go in for such a pro­ce­dure. It would wiser to in­vest in a new motorcycle with fuel-in­jec­tion. We hope you find the right FI motorcycle for your needs.

Tube­less Tyres and Spoke Wheels

I have a Royal Enfield Bul­let 350 and I go on long trips at least once in two months. Fol­low­ing nu­mer­ous punc­tures, I am con­sid­er­ing chang­ing to tube­less tyres as they are more con­ve­nient to re­pair. I heard that spoke wheels can be shod with tube­less tyres af­ter seal­ing the in­side of the rim. Is it ad­vis­able to do so and will it have a neg­a­tive ef­fect on the han­dling?

Ra­jesh Bi­hari, Lucknow Dear Raj, it is true that tube­less tyres are eas­ier to re­pair as you don’t have to dis­mount the tyre from the rim to re­pair a punc­ture. How­ever, it is not pos­si­ble to fit a tube­less tyre to a con­ven­tional spoke wheel. There are bikes that do come with spoke wheels and tube­less tyres, but they use spe­cial wheels where the spokes are fit­ted in re­verse and the in­side of the wheel is com­pletely sealed, just like an al­loy wheel. In­stead, we would rec­om­mend that you use good qual­ity tyres and keep them in­flated to the right tyre pres­sure that should keep the num­ber of punc­tures to a min­i­mum.

Spares for the Yamaha RD350

I am an avid reader of your mag­a­zine. I heard re­cently that Yamaha pro­pose to start pro­duc­ing the RD 350’s spares. When do you think these will be­come avail­able in ma­jor In­dian cities? What is a CDI kit? Which is the most ap­pro­pri­ate disc brake and CDI kit for the Yamaha RD 350 (1984 model)? Where and at what price may I find those in New Delhi?

No, Yamaha have not started pro­duc­ing any spare parts for the RD 350 nor will they, so far as we know, in the near fu­ture. There are a num­ber of CDI kits avail­able in the mar­ket. We sug­gest that you go for a 12V RX135 ig­ni­tion sys­tem that would fit your bike well. As for fit­ting disc brakes on your RD 350, you will have to weld the lugs on to the front forks for caliper mount­ing. Then you will need to re­place the front wheel with one that has mount­ing points for the ro­tors. You may con­sider the disc brake assem­bly from the Pul­sar or Yamaha FZ. Have the whole thing done by a com­pe­tent me­chanic or else there are chances that the whole mod­i­fi­ca­tion job might just back­fire.

Slug­gish in Du­cal Com­par­i­son

I have a ques­tion re­gard­ing my Ba­jaj Pul­sar 200NS. My bike has done 20,000 km, but I am not re­ally happy with its ac­cel­er­a­tion. I want my bike to have the same ac­cel­er­a­tion as the KTM 200 Duke. Please sug­gest to me how it may be done.

Di­wan Zo­rawar, via e-mail

The main rea­son why the bike feels slug­gish as com­pared to the KTM is that the Pul­sar 200NS is heav­ier than the Duke. Be­sides, it has taller gear­ing and is slightly less pow­er­ful. To make your bike go as fast as the Duke, you would need to un­der­take a num­ber of mod­i­fi­ca­tions to re­duce weight, im­prove gear­ing and in­crease the power, all of which is not re­ally worth the time and money. In­stead, you can al­ways con­sider up­grad­ing to the Duke.
